House Helmawr

House Helmawr is the ruling Noble House of the planet Necromunda. Also called the Ruling House, Imperial House, Royal House of Necromunda, Guardians of all Necromunda or Lords of the Spire, they use a hereditary system of succession, with the leader of the house (styled Imperial Commander Lord Helmawr, Adeptus of the Imperium of Man, and Guardian of Necromunda in the Holy Name of the Undying Emperor) being the Planetary Governor of the planet, in effect personifying Necromunda to the Imperium, and representing the Imperium to the inhabitants of Necromunda.
